Bottleneck Gallery will have new alternative poster prints for Evil Dead 1 & 2 by artists Adam Perocchi and Jack Gregory up for sale this Friday (3/29) @ 12pm EST.
Adam Savage recently got his hands on the (unofficial) Magnoli Props Tobin's Spirit Guide replica, which contains a number of easter eggs to franchises beyond Ghostbusters. The Necronomicon (based on it's appearance in Evil Dead 2) appears in the book, and contains a detailed description (copy-pasted from Wikipedia and the Evil Dead Wiki with minor tweaks) that attempts to merge the Evil Dead version and the original Lovecraft tome (and maybe another franchise's version?)
Cellar Door Gallery has an officially licensed limited edition screenprint Evil Dead 2 poster by David Seidman going on sale October 31st. The normal version (blue) will limited to 100, while the variant (mint green) will have 50.
I guess this qualifies as fan art... that you can digitally interact with. Someone recreated the Halloween Horror Nights Evil Dead Rise haunted house attraction in Roblox. Pretty faithful recreation!
